Threat Modeling: Protecting Our Nation’s Software-Intensive Systems

While understanding cyber threats to complex software intensive systems is important, identifying threats and mitigations to them early in the design of a system helps reduce the cost to fix them. In response to Executive Order (EO) 14028, Improving the Nation’s Cybersecurity, the National Institute of Standards and Technology (NIST) recommended 11 practices for software verification. Threat modeling is at the top of the list. In this podcast from the Carnegie Mellon University Software Engineering Institute (SEI), Natasha Shevchenko and Alex Vesey, both engineers with the SEI’s CERT Division, sit down with Timothy Chick, technical manager of CERT’s Applied Systems Group, to discuss how threat modeling can be used to protect software-intensive systems from attack. Specifically, they explore how threat models can guide system requirements, system design, and operational choices to identify and mitigate threats.
